You can use Full Moon Dance to move damage counters around, or Moon Skip to take an extra Prize card if you are successful in knocking out one of your opponents Pokemon
Also, perhaps you have a monster that can attack more than once, but only if it destroys another monster by battle first, like Chimeratech Overdragon, or cannot attack directly, like Vision HERO Trinity
